You are so very correct! I have copied a couple of excerpts from: http://www.thepublicdiscourse.com/2009/05/229/

"The senators who originally designed our family planning policies believed that the mostly black welfare population was incurably lazy, promiscuous, intellectually substandard, and a burden on public schools, and, moreover, that they probably would remain so indefinitely. Birth control, therefore, was in their eyes a way to reduce the number of these undesirable people. This article is the second installment in a three-part series.

The stimulus package of 2009 originally included millions of dollars for family planning services each year. Speaker Nancy Pelosi defended this extra funding as a means of saving money, noting that by reducing births to the poor, the government could lower its welfare costs. In the first article in this series, I showed that this idea was already central to U.S. family planning policy as far back as the Nixon administration. In fact, family planning is currently the most favored service of Medicaid, and the federal government spends over $1 billion annually in order to suppress the birth rate of the poor. By law it must encourage poor girls who have reached puberty to begin using contraception. These policies have been in place since 1972, when the welfare laws were changed to impose a national family planning policy on all the states at once, overriding the local laws that generally encouraged parental consent. These provisions were written by the Senate Finance Committee during the first major overhaul of Lyndon Johnson’s Great Society welfare laws.

This article appeals to transcripts from the committee hearings to argue that the committee enacted these policies out of r****t, eugenicist motives. While the motives behind the American welfare system were originally idealistic—providing temporary assistance to needy families while they climbed out of poverty—the committee hearings show that the senators believed that the mostly black welfare population was incurably lazy, promiscuous, intellectually substandard, and a burden on public schools, and, moreover, that they probably would remain so indefinitely. Birth control, therefore, was in their eyes a way to reduce the number of these undesirable people."
